Seems a bit pointless to me to do all that work... Just connect 2 Juno-106s over MIDI...

This.

Also add the fact that it looks extremely tacky and awkward to play on. Look how far out he has to extend his arm just to tweak the upper controls, plus now if you want to play the sounds on separate keys, you'd need to plug in a MIDI controller making the set up even more ridiculous looking. Might as well add spinning rims and a cup holder too.

I like the new tone color possibilities with the dual filter architecture, and "polyphonic filter frequency modulation of the master synthesizer’s filters using the slave's synthesizers voices as mixable modulation sources" sounds intriguing...
